Taxonomy-based links with primary link to homepage

So far I have a site which is based entirely around a single vocabulary. I have the primary and secondary links generated depending upon the selected term. So far, so good; however, one of the terms is 'Home' which should display the associated secondary links (careers, about the company, etc) but also link to the homepage. Now the problem arises: the link is to http://blah.com/home and not just to http://blah.com so the home page isn't shown. If I change the homepage to http://blah.com/home and use the global redirect module to force it to http://blah.com then the correct secondary links don't appear and I also can't select 'Show on homepage' for any relevant articles.

I guess my question is: Is there a sensible way to put a homepage link and have the appropriate secondary links displayed or do I have to just hack the PHP to make this happen? The hack isn't complex but it's hardly in the spirit of things.
